    Hi guys and gals!

    You’ve probably heard about Google Cardboard somewhere (if not I will tell you in a second) and how you can easily assemble one for yourself. Unfortunately our OPOs are slightly too big for the standard ones. Buttons are being pressed by accident, and it just doesn’t look very sexy. Of course there are some larger models on the market, but since I like creating/designing stuff myself I made a OnePlus version! And that’s not all: you can download my template here and start assembling your own! :D

    Google Cardboard?
    If you don’t know what Google Cardboard is don’t worry, I’ll explain. Maybe you know about Oculus Rift, the Virtual Reality (VR) headset? In essence the Google Cardboard is the same. One difference is that you can create your own Cardboard headset rather easily and it’s really cheap. As the name suggests it is made out of cardboard, which you simply fold. To get it working you just need some small extra parts like lenses, magnets and Velcro. The Google Cardboard app lets you play some demos, but there are more and more interesting third-party apps and games appearing in the Play Store.

    The template
    The problem with the original Cardboard template is that it’s slightly too small for our beloved OPOs. It just doesn’t look very sexy (remember the OnePlus blog?)… Therefore, I decided to make my own custom OnePlus version. I tested and modified this template until I was satisfied and I really, really like it. For this reason I want to share it with you here. I made two templates for you to download: an A4-size template and (for the people in the US) a letter-size version. You can download them here:

    What else do you need?
    Before you can start with assembling your own OnePlus-compatible cardboard VR headset you will need to purchase and collect some stuff. I ordered most of the “ingredients” online on websites like Ebay, which resulted in 3-4 weeks of waiting for the shipments to arrive. If you are lucky you could find most of the items in a (specialised) hardware store, but I doubt you can find the right lenses or NFC-tags there. I would recommend you to collect all ingredients on beforehand, because it is much more fun to assemble the headset in one go.

    1. Cardboard
      Of course the most important ingredient of the headset is the cardboard. You can probably buy this in a local hobby shop, but it is cheaper, environmental friendlier, ánd more fun to collect it from waste-paper bins. I collected some very nice pieces of cardboard from the waste-paper bins at my university’s faculty of Architecture. The minimum size of the cardboard should be somewhere around 62 x 25 cm (that's 24.5 x 10.25 inches). Make sure there are no folds in the cardboard. Google advises to use cardboard with a thickness of 1.5 mm (0.06 inches). I think mine was slightly thicker. This only meant that I had to adjust some of the cuts and holes when folding the headset.

      [​IMG]

    2. The lenses
      Perhaps the hardest part is to find the right type of lenses. These lenses are so-called “biconvex lenses” and have a focal distance of 45 mm. They should have a diameter of around 25 mm. I bought these: http://tinyurl.com/p4t8pa9 (note: 1 piece contains a set, so 2 lenses!).

      [​IMG]

    3. Two types of magnets
      You will need two different types of magnets for the switch used for controlling the headset. One of them is a “ferrite disk magnet”, the other one is a “neodymium ring magnet”. Both should have a diameter of around 20 mm (0.75 inches). Thickness may vary between 3-5 mm (0.12-0.20 inches). Unfortunately you cannot just buy one magnet of each. Instead, they are mostly being sold in bulks of 5 or 10 pieces. I bought these: http://tinyurl.com/nm9bzha and these: http://tinyurl.com/kwmpupk

      [​IMG]

    4. Velcro strips
      The Velcro is used for opening and closing the back of the headset, where you put your phone. Use adhesive-backed Velcro with a width of approximately 20 mm (0.75 inches). Something like this: http://tinyurl.com/ltmmnpw (select 1 meter and “hook & loop”). For the Dutch people, I bought this at the local Hema store: http://tinyurl.com/l2ucnvn

      Optional: Velcro headband. If you don’t want to hold the headset while using it you might want to attach a Velcro headband to it. Something like this will do: http://tinyurl.com/m9ft9rv

      Tip: use a bit of super glue to glue the Velcro to the cardboard. Although it is adhesive-backed, the Velcro tends to come off under pressure. And you really don’t want your phone to fall down and crash onto the floor…

      [​IMG]

    5. NFC-tag (optional)
      You can stick an NFC-tag onto the headset if you want to automatically start the Google Cardboard app once you put your phone into the headset. These stickers will work with our OPOs: http://tinyurl.com/o2jum67 (sold in batches of 5 or 10 tags).

      [​IMG]

    Once you have collected all of the ingredients you are ready to move on to the next step: cutting and assembling, yeah! :)

    Cutting and assembling the OnePlus VR headset

    Now that you’ve collected the ingredients we can start with creating the headset. You will need some additional tools though, which are shown in the photo below (click on it to see a bigger image):

    [​IMG]
    Ingredients and tools you need (clickie-click!)

    Step-by-step plan
    Down here is a step-by-step tutorial on how to cut the headset and assemble it.

    1. Prepare the template

    Print out the template on regular paper (so not too thick) and cut it out. The numbers on the template tell you where to glue two different parts of the template together: glue the white number 1 on top of the black number 1, the white number 2 on top of the black number 2, and so on. If you hold the paper in front of a light source or your window you can do this rather precise. In the end you'll have this:

    [​IMG]

    2. Cut the cardboard

    Attach the template to the cardboard by using some tape. Start with cutting the cardboard along the solid black lines. You can try scissors, but I would recommend you to use a sharp knife and a ruler. This will make sure that the edges of the cardboard are smooth.

    [​IMG]

    Continue with cutting all the solid black lines, including the small holes (the hardest part). Start folding the cardboard along the red dashed lines. To make sure you fold the cardboard in the right places you can attach the template back on top of the cardboard. In the end you'll have this:

    [​IMG]

    3. Fold the headset

    Take the lenses and place them like explained in the template.

    [​IMG]

    Fold the cardboard and glue (permanent) or tape (less permanent) it together. This is personal and thus up to you :p

    [​IMG]

    Start folding the largest piece of cardboard, like this:

    [​IMG]

    Fold the flap, take the two magnets, and affix them to either side of the cardboard. The disk magnet is placed into the hole while the ring magnet is affixed on the opposite side of the cardboard. Like this:

    [​IMG]

    And this:

    [​IMG]

    Now take the other cardboard pieces and attach them to the largest cardboard piece. You might need to trim some of the holes and edges of the cardboard a little to make sure that everything fits nicely. Now you'll have something like this (I didn't use glue or tape here for the sake of making the tutorial, so it looks kinda odd :p):

    [​IMG]

    Attach the flap on top of the headset, trim some holes and edges if necessary, and glue or tape it all together. Like this:

    [​IMG]

    And this:

    [​IMG]

    4. Create the Velcro closures

    Prepare the Velcro by cutting 4 pieces of both strips (so 4 pieces with hooks and 4 pieces with loops). My pieces were around 3 cm in length (1.20 inches). To make sure that the hook and loop strips of each closure are equal in length just attach them to each other before cutting, like in the picture below:

    [​IMG]

    Remove the backing paper and attach the Velcro strips to your headset. You might want to use some extra super glue to make sure it is securely attached to the cardboard, because my experience is that the Velcro tends to come off under pressure (for instance when your phone is inserted).

    [​IMG]

    Create two closures on top of the headset:

    [​IMG]

    And two on the extra flaps I designed to keep your phone in place.

    [​IMG]

    Like this:

    [​IMG]

    Now the headset is completely assembled and you are almost ready to play with it! :D

    If you want you can customize the headset by giving it some color. Or by attaching a nice OnePlus sticker for instance, like I did:

    5. (Optional) Add and program the NFC-tag
    You can now start with exploring the various Cardboard compatible apps and download them. Once downloaded just start an app and put your phone into the headset. But wouldn’t it be fun if your phone automatically starts an app upon inserting it into the headset? It’s possible!

    An NFC-tag makes it possible to start an app once your phone makes contact with it. In order to make it work you need to program an empty tag. I used the NFC tools app: https://play.google.com/store/apps/details?id=com.wakdev.wdnfc&hl=nl

    Grab an empty NFC-tag and stick it onto the outer flap of the headset:

    [​IMG]

    Open NFC Tools and scan the tag. You will see some cool information about the tag itself and whether it is empty of not (shown at the bottom):

    [​IMG]

    Now we want to program the NFC-tag in such a way that it opens the Cardboard app. In order to do so go to “Write”, select “Application”, and click on the Android icon:

    [​IMG]

    From the following list select “Cardboard”. Now choose “Write”. A pop-up shows saying “Approach an NFC Tag”. So again, scan the empty tag you just attached to your headset.

    [​IMG]

    After scanning the NFC-tag it will say “Write complete!”. Close the NFC Tools app. Once you approach the tag in your headset it will automatically open the Cardboard app! From there you can start every Cardboard compatible app you’ve installed on your phone.

    Have fun! :D

    There is a larger version of the Google Cardboard available for bigger phones like 6 Plus, OPO, Note X, etc. I bought one about a week ago and so far I am loving the experience.

    Good job with the template:)

    I have the Google cardboard but was wanting a material that would be more durable like plastic or a packing sturdy packing foam type thing. This is a great post to get the dimensions right for the opo.
    Favorite VR app "Sisters" it made me jump.
